If you use Bitcoin or other payment method simply email me.
You may be interested in a Bitcoin-based merchant service provider, depending on how much time you want to spend on integrating one with your site. That would allow for more automation.

Thx. I already use bit-pay in Superadaptoid:http://nestorgames.com/superadaptoid_detail.html
...but the problem is that I charge a fixed shipping fee (9 Eur) no matter how many games you purchase, but Bit-pay doesn't support this feature (yet).
Sure they do, just add a "shipping" item to the cart. Variable shipping would be harder though.
Good idea. But it won't be automated
I haven't tested it, but I just hacked this up: http://pastebin.com/3p9YvqL7
If you replace the dataForItem and dataForShipping, it should work. However, if your customer adds multiple items like this, they will get duplicate shipping charges and will need to delete one. Kinda messy. Bit-pay really should add at least minimalistic shipping support.
